| ## 9.12\. Data Deletion |
| |
| All device implementations: |
| |
| * [C-0-1] MUST provide users a mechanism to perform a "Factory Data Reset". |
| * [C-0-2] MUST delete all data on the userdata filesystem. |
| * [C-0-3] MUST delete the data in such a way that will satisfy relevant |
| industry standards such as NIST SP800-88\. |
| * [C-0-4] MUST trigger the above "Factory Data Reset" process when the |
| [`DevicePolicyManager.wipeData()`]( |
| https://developer.android.com/reference/android/app/admin/DevicePolicyManager.html#wipeData%28int%29) |
| API is called by the primary user's Device Policy Controller app. |
| * MAY provide a fast data wipe option that conducts only a logical data erase. |
